Abstract: <p>Sustainable development is normative - making decisions in the present that construct the experience of place for the future. It is primarily driven by global measures developed to meet the needs of the present while ensuring future generations can meet their own needs. These measures attempt to balance economic prosperity, social justice, and environmental stewardship in many nations.… more

Abstract: <p>This study assesses the ability of a unicellular protist, Euglena gracilis, to remove Cu and Ni from solution in mono- and bi-metallic systems. Living Euglena cells and non-living Euglena biomass were examined for their capacity to sorb metal ions. Adsorption isotherms were used in batch systems to describe the kinetic and equilibrium characteristics of metal removal. In living systems… more

The present work shows that high molecular weight of TPEUs with enhanced performance can be obtained from lipid-derived monomers… more

Abstract: <p>This study examines the influence of dissolved organic matter (DOM) on dissolved vanadium (V) speciation in the Churchill River and Great Slave Lake using diffusive gradients in thin film (DGT). Vanadium is commonly found in natural environments such as rivers, lakes and oceans. It regulates normal cell growth, but in excessive amounts, it can have toxic effects on human and aquatic… more

Abstract: <p>Based on an endogenous hormone study, three cytokinin type phytohormones; benzyladenine (BA), trans-zeatin (tZ) and methylthiol trans-zeatin (MeSZ), as well as abscisic acid (ABA) were exogenously added at three concentrations (10-7, 10-6 and 10-5 M) to cultures of Chlorella vulgaris in an attempt to alter growth rate, total lipid and fatty acid yields and fatty acid profile. Growth… more

The ontological question is elaborated in terms of a theory of the spatial-temporal structure of the aesthetic or sensible realm. This… more

The films being studied are El Sol del Membrillo by Victor Erice and Rivers and Tides by Thomas Riedelsheimer. My approach to critical topography in the thesis is twofold: first, I have traced the topical motifs that have appeared to me as I looked at the two films; second, I… more

Abstract: <p>Since British colonization of North America and the beginning of Anglo-speaking Euro-Canada and the United States, myth-making or representations of the forests have witnessed degradation and loss of old-growth forest ecosystems or intact sylvan landscapes. Canadian and American versions of the story of the North American Forests shared the same trajectory: forests as 'wasted-land… more

Abstract: <p>This thesis sought to explore and evaluate perceptions of food needs and the role of a community freezer in addressing those needs, among Inuit in Hopedale, Nunatsiavut (Northern Labrador). Research was carried out through an exploratory sequential mixed-methods design. Phase 1 employed qualitative interviews with community members in Hopedale to explore the perceptions of food needs… more

Abstract: <p>This thesis investigates the organization and development of water management systems in a sample of past tropical societies in Southeast Asia and Mesoamerica. A comparative approach is employed to show how water management affected the trajectories of the ancient states of Angkor, Cambodia, Bagan, Myanmar, Sukhothai, Thailand, Central and East Java, and Caracol, Belize. Differing types… more

Abstract: <p>In the context of Real-Time Bidding (RTB) the machine learning problems of</p><p>imbalanced classes and model selection are investigated. Synthetic Minority Oversampling Technique (SMOTE) is commonly used to combat imbalanced classes but a shortcoming is identified. Use of a distance threshold is identified as a solution and testing in a live RTB environment shows significant… more

Abstract: <p>This thesis explored the contribution of mixed methods approaches to marine mammal science through the use of concurrent and sequential designs to study distribution and feeding ecology of bowhead whales (Balaena mysticetus) in the Arctic region of Nunavik, Quebec, Canada. The study combines Inuit knowledge (IK), collected through semi-directed interviews with Inuit harvesters, and… more

Abstract: <p>A sample of faunal remains (n=129) from seven archaeological sites located on Pigeon and Rice Lakes, Ontario were sampled and analyzed for the stable carbon and nitrogen isotopic composition of bone collagen. These samples date from the Archaic to Late Woodland and include 35 different animal species. The goal of this research was to investigate the isotope ecology of the Middle Trent… more

Abstract: <p>This study intervenes into the debate regarding the definition of pluralism in ecological economics and how that definition affects various characterizations of ecological economics. The methodological pluralist camp argue for the inclusion of neoclassical economics into the ecological economics fold, while the critical pluralist camp argue against the inclusion of neoclassical economics… more

Abstract: <p>In this work, various aspects of neural networks, pre-trained with denoising autoencoders (DAE) are explored. To saturate neurons more quickly for feature learning in DAE, an activation function that offers higher gradients is introduced. Moreover, the introduction of sparsity functions applied to the hidden layer representations is studied. More importantly, a technique that swaps the… more

Abstract: <p>The assessment of visuomotor function can provide important information about neurological status. Several visuomotor tasks exist for testing in the laboratory, although attempts to make these tests portable to allow quick and reliable assessment have been limited. We developed an assessment tool using two laboratory visuomotor tests as a tablet application: the double-step task, and an… more

Abstract: <p>This thesis examines the spatial, temporal, and contextual distribution of copper bells in the Greater Southwest region and how they are situated in archaeological literature. To date, 672 copper bells have been found in at least 113 different Southwestern sites dating from ca. A.D. 900-1450, though there is no archaeological evidence for metallurgical activities in the area at this time… more

Abstract: <p>Previous research has suggested that childhood sensory sensitivity may predict adult obsessive compulsive (OC) behaviours. To date, however, research has not addressed how the separate dimensions – harm avoidance and incompleteness - may influence this relationship or why it exists. The current study used a retrospective design to test a) if sensory sensitivity in childhood predicts… more
